in a genealogy over 100 years ago, the last name of a relative’s second husband was incorrectly typed as “Crown.”
Turns out that the last name was actually Brown. This was discovered when the estate file of the first husband was read completely. In the first reference to the widow with her new last name, it sort of looks like Crown. But there are three later references where it is clearly Brown.
Sure enough the widow was found in other records as “Brown.”
